If you google "government spokesperson says US has bio labs in Ukraine" you go through 24 articles where the US denies any bio labs in Ukraine but the 25th article on page 3 says: On Tuesday, Undersecretary of State Victoria Nuland stated before a Senate hearing that “biological research facilities” have been operating in Ukraine, in response to a question from Senator Marco Rubio (Republican of Florida) about the presence of chemical or biological weapons in the country. She said the US has nothing to do with these labs but she was concerned that they might fall into Russia's hands.
